Steve H Lakewood , CO October 26, 2019 Dryer overheating and shutting off I replaced the thermal shutoff, and two other thermostats-one in the heater plenum and the other near the fan vent. No dice. I think now it might be the motor thermal shutoff and the motor is going bad. Onward! Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
